I have a 40 panel 10.4kw ground mounted array in western NY. It is facing dead south and is almost zero obstruction. Production was 2016 - 13.2 Mwh, 2017 12.4 Mwh, 2018 11.7 Mwh. Year to date is 1370 kwh. It all comes down to location (42.7190° N) and how much snow piles up on the panels in the winter. Solar is not even close to viable here. I put it in when it was about 60% subsidized by the state and the feds. That made is about a 10-11 year payback. Our rate including delivery is $0.10/kwh.
